Cores 2WAY Tumbler Black C570BK 450ml

The 2-way drinking spout and double vacuum insulation structure keep the drink fresh for a long time. The spout can be used either through a straw or directly from the bottle. The straw can be removed and washed. The double-walled vacuum insulation prevents condensation on cold drinks and prevents hot drinks from burning, allowing you to keep your drinks comfortable and delicious for a long time. The lid is screw-on and seals tightly, and the drinking spout also clicks shut, so there is little risk of leakage. The stainless steel (SUS316L) used is durable, corrosion-resistant, and hygienic, and is a material that is also used in medical equipment. The design is accented with rolled up covers, making this stylish pair of tumblers a great gift set.
